Infrastructure & Transit
Rugged. Modular. Rapid deployment. Built for sites that don't wait.
Infrastructure projects — railways, highways, metro stations, airports, and smart-city installations — need water treatment that can be deployed fast, survive harsh conditions, and meet regulatory requirements from day one.
Industry Challenges
What makes infrastructure & transit water treatment complex.
Every industry has unique water treatment requirements. Understanding these sector-specific challenges is the starting point for every NWPL project.
Construction site STPs must be functional within 30 days of mobilisation — standard civil construction timelines don't fit. Modular pre-commissioned skids are the only viable solution.
Metro stations and railway depots generate workshop effluent (oil and grease, suspended solids, heavy metals from brake and wheel wear) that requires specialist treatment before discharge.
Smart-city water treatment for parks, public toilets, and civic centres must be unmanned and remotely monitored — NWPL's IoT platform enables this without on-site operators.
Airport and seaport waste water treatment must operate 24/7 with zero downtime tolerance — redundant systems and emergency response contracts are mandatory.
Highway rest stops and toll plazas in remote locations generate sewage without access to municipal sewers — compact containerised STPs are the only compliant option.
Our Solutions for Infrastructure & Transit
Technology matched to your site.
Compliance Requirements
Infrastructure projects face multiple regulators simultaneously.
NWPL systems are designed to meet every applicable standard for your sector — from the day of commissioning.
MoEFCC EIA Notification
Environmental clearance requires commissioned WTP/STP for all projects >5000 m²
CPCB / SPCB Consent
Consent to Establish and Consent to Operate for all treatment facilities
NHAI Green Highway Policy
Water treatment requirements for highway rest areas and service zones
Smart Cities Mission (MoHUA)
IoT-monitored water systems as mandatory for Smart City infrastructure projects
RERA (Commercial & Mixed Use)
Mandatory STP for commercial and mixed-use developments before occupancy certificate
Featured Projects
Proven in infrastructure & transit.
Metro Depot ETP — 200 KLD, Mumbai Metro
Workshop effluent (oil and grease 1,200 mg/L) treated to <5 mg/L. Heavy metals (copper, zinc) removed to CPCB limits. Treated water reused for depot vehicle washing. BMC consent obtained.
Smart City STP Network — 8 Locations, Navi Mumbai
Eight compact containerised STPs for public parks and civic centres. All remotely monitored from single NWPL dashboard. Zero on-site operators. 98.6% uptime in 18 months.
